Seems it's not work, extra operating current @500mA for iPhone is not appeared in System Information -> USB
The screen shot shows the iPhone is connected as a high-speed device, for which 500mA is max. The extra-current errors are for super-speed devices only
. They leave a message like this in system.log
The IOUSBFamily did not receive enough extra current for the SuperSpeed device ____ at _____, asked for 400mA but got 0 mA
Rampage Dev: The message
WaitForCMD: Timeout waiting for command completion, 100ms
indicates the xhci controller in stalled. The KP later is in Apple's code (AppleUSBHub), probably because the controller is stalled and returning errors AppleUSBHub doesn't process well. I'll need to see a xhcdump of the controller state. Maybe with no connected devices it won't KP so xhcdump can be recorded.
68x: Usually it's because auxillary power is not supplied to the xhci chip during sleep.
